==Overview==
During the third week there appears, immediately behind the ventral ends of the two halves of the [[mandibular arch]], a rounded swelling named the [[tuberculum impar]], which was described by His as undergoing enlargement to form the buccal part of the [[tongue]]. More recent researches, however, show that this part of the tongue is mainly, if not entirely, developed from a pair of '''lateral swellings''' (or '''distal tongue bud''') which rise from the inner surface of the mandibular arch and meet in the middle line.
